NEW ORLEANS -- A retired well about 75 mi off the Louisiana coast is leaking natural gas and light oil, accord. The leak prompted the evacuation of five workers from a three-well production platform owned by privately-held Talos Energy.

U.S. Coast Guard officials are monitoring a hydrocarbon sheen on the surface, which extends about 4 mi from the well site. The Fuel Fix energy blog reported a Talos crew was permanently plugging and abandoning the decades-old well when it noticed the leak.

Talos Energy President Timothy Duncan told Fuel Fix the company plans to return crew to the field and expects to have the well under control within the next 24 hours.
